because of that. in mexico, for instance, the variation of time was 1 1/2 meters. as you can see there, when that happened, 3.34, immediately we have different waves. the high of that wave was at about 50 meters but one hour after that in one place we start having waves of 30 meters. a happened in the island of guata after that, 7:00 in the morning we are still having different waves at different places in the coast arriving every 30 minutes and the average high was about 15 meters, which is a lot. another massive effect was that the south american plate jumped over nafka plate, or nafka plate gets down. we moved 3 meters to the west and at the same time we lift up at about 3 meters in certain areas. so navy -- this is very important because in some places where you are supposed to get into with your ships, not any more. so a hydrographic survey, certain port was absolutely mandatory when you have this event. i said to the australian staff, because of that we are closer neighbors right now. here you can see an example that was before the earthquake, the distance of the low tide.
